Propagation of Microwave Phonons in Germanium

Abstract

The effects of various kinds of interactions on the propagation of 9 GC microwave phonons in germanium have been studied experimentally. We will discuss phonon interactions 1) with conduction electrons in degenerate n – Ge, which produces attenuation of waves of specific polarization in particular directions of propagation, 2) with thermal phonons, which gives temperature dependent ultrasonic attenuation, 3) with microwave phonons, which gives nonlinear effects.
